Securing the Hive Metastore Database

It is important to secure the Hive metastore, so that users cannot access the names or other information about databases and tables the through the Hive client or by querying the
metastore database. Do this by turning on Hive metastore security, using the instructions in the CDH 5 Security Guide for securing different Hive components:

Secure the Hive Metastore.

In addition, allow access to the metastore only from the HiveServer2 server, and then disable local access to the HiveServer2 server.
